FEEDING MECHANISM FOR TALKING-MACHINES.

Specification of Letters Patent.

Patented July-14, 190s:

Application filed December 18, 1906. Serial No. '347,682.

. siding at Uhlandstrasse 13, 'm Schramberg,

Germany, have invented certain new and useful Improvements in FeedingMechanism for Talking-Machines, of which the following is a full, clear,and exact descri tion.

This invention relates to fee ing mechanism for' talking machineswherein "the diaphragm su porting tube can slide on roller guides witout any articulation in a tube connectedto the sounding trumpet.

In order that with such feeding mechanism .thesliding or forwardmovement of the dia' phragm tube may take place independently of therecord rooves of the record disks, the diaphragm tu e according'to thepresent invention is moved forwards by means of a slide operated by thedriving ear of the machine, said movement being 0 course always suchthat the feed of the diaphragm and style conforms with the spiral ofrecord grooves on the record disk.

The accompanyin drawing shows a form of construction of t e presenttransporting device. I

Figure-1 is a side elevation with partial section; Fig. 2 is a sectionon line AB and Fig. 3 is a section on line C'D of Fig. 1.

. The 'tube a bearing the sounding trum et in the usual manner isadjustably mounte in a bracket arm I) fastened to the box of the talkingmachine. In this tube a extends the tube 0 at the outer end of which issecured the part dsupporting the dia hragm. Thetube c-slides bn rollerse exten mg on the one hahd throu h recesses of the tube a and bearing oncomprises the racket f provided with rollers or rotary disks and theguide bar 9. The

. ingly lengthened s latter moves within the bracket arm I) and issupported in its forward-part by a roller 71.

It moves between two friction rollers j and k,

the lattel; of which is .arran ed on a readily interchangeable shaft 1.T ere is mounted on this shaft aremovable worm wheel m engaging in aworm n set in rotation from the driving gear of the machine. The drivingotion of the worm may be derived from the riving gear insuch a mannerthat the spindle h receiving the record disk is likewise provided with aworm 11; where in the correspondgear is. roportioned in such a manner.that the fee of the slide and diaphragm suppert-- aft 0 of the worm :11.en- 'gages by means of the worm wheel r. The

diaphragm may be readily adapted to the actual type of disk by mountinga suitable Worm wheel thereon. T

What I claim as my invention, and desire to secure by Patent is: v

In a talking machine, the'combination of a diaphragm, and means formoving said dia- Y hratgm" including friction rollers and means orriving said friction rollers includin worm gearm having an intermediateshaft I and worm W eel m, and means for mounting such shaft and Wheel sothatthey may be easily removed.

In witness whereof, I have. hereunto si ed WM. HAHN.
